We conducted a feasibility study to evaluate micronutrients and body mass index. Fat soluble vitamins A, D, E and trace elements copper (Cu), selenium (Se) and zinc (Zn) levels were evaluated. Weight, height, body mass index (BMI) and Z-scores were recorded. Side effects or specific adverse events were documented. No patients had a Z score for height, weight, or BMI of <2SD or >2SD. Ninety percent of patients had one or more micronutrient levels below normal. These results suggest that micro-nutrient abnormalities are common despite no obvious evidence of malnutrition. Side effects of chemotherapy may be exacerbated by micronutrient depletion.
